Upside-Down Pizza Casserole

Play with this four-ingredient recipe just as you would improvise with pizza toppings. You can substitute Italian sausage for the ground beef or add ingredients such as sliced mushrooms, pepperoni or sweet peppers into the meat mixture.

Ham and Mushroom Lasagna

This creamy, crazy-delicious lasagna is simple, too, thanks to jarred Alfredo sauce and no-boil noodles. If you're lucky enough to have a specialty grocery store or Italian deli that sells all-natural refrigerated Alfredo sauce without preservatives, this is a great way to use it.

Butternut Squash Bake

This creamy squash casserole calls for mascarpone—a mild, soft, butterlike cheese—as well as Parmesan. You can substitute softened cream cheese for the mascarpone if you prefer. Time-saver: Look for precut squash in your supermarket. (You can also bake the squash in your oven first to make it easier to peel and cut.)

Tuna Alfredo Casserole
